And you are not very likely to get it, because there is no such
thing as "LLVM lex" or "LLVM parse".

I think you are still erroneously conflating LLVM with its frontends
like llvm-gcc and clang. It is perfectly possible to utilize LLVM
as if it were the system's native assembler. Simply make your compiler
generate a text representation of the IL, and use LLVM's command line
tools to produce the native executable.
